A medium-sized, pittalike bird of sub-alpine forest floor. Brown head and upperparts extending to the sides of the chest, pale gray underparts, with whitish throat, center of the belly and sometimes some scalloping on the chest. Note the strong bill and long legs. Shy and difficult to see. Same general shape and habits as the Lesser Ground-Robin, but Greater occurs at higher elevations and is much larger. Much more often heard than seen. Very distinctive, short, whistled phrase sounding like ‘What do you think?’ with the last note upslurred.
